Abstract:
(EN) The present invention provides an ethylene-vinyl alcohol copolymer composition that suppresses coloration and contains an ethylene-vinyl alcohol copolymer (A), a polyamide resin (B) and an iron compound (C). The ethylene-vinyl alcohol copolymer composition has an iron (C) content of 0.01 to 20 ppm in terms of metal per the weight of the ethylene-vinyl alcohol copolymer composition.
(FR) La présente invention concerne une composition de copolymère éthylène-alcool vinylique qui supprime la coloration et contient un copolymère éthylène-alcool vinylique (A), une résine polyamide (B) et un composé de fer (C). Cette composition de copolymère d'éthylène-alcool vinylique possède une teneur en fer (C) de l'ordre de 0,01 à 20 ppm en termes de métal par poids de la composition de copolymère d'éthylène-alcool vinylique.
(JA) 着色が抑制されたエチレン-ビニルアルコール系共重合体組成物として、エチレン-ビニルアルコール系共重合体(A)、ポリアミド系樹脂(B)および鉄化合物(C)を含有するエチレン-ビニルアルコール系共重合体組成物であって、上記鉄化合物(C)の含有量が、エチレン-ビニルアルコール系共重合体組成物の重量あたり、金属換算にて0.01~20ppmであるエチレン-ビニルアルコール系共重合体組成物を提供する。
